'Be itlknown'that I, EMORY E. Tnownninen, a citizen of the United States, the 'cityof Kansas City, county of Wyandotte, and State of Kansas, have nvented certain new and useful Improvements in Drain-Tiles, specification.

of which the .following is a 1 My invention relates to improvements in drain tile and refers. more. particularly to a cup socket tile used inydrainage systems to carry off superfluous moisture from 1mproperly drained subsoil.

Among its salient objects are to provide a type of drain tile constructed to facilitate:

a the removal of moisture from the subsoil;

to provide a drain tile which when Connected to form a drainage systemproduces a more mobile circulation of the water andair in the subsoil and to permeate more. quickly to the body of the soil, causing the e t 7 u more'readily therefrom; to provide a draln a tile that is not easily waterlogged and tiles thataare adapted to be connected up-lnany drainage system; to provide a tile that is cheap to manufacture and tile sections that are easily connected into ,a. system, andin inF'ig. 2. i I

or a vitrified clay is commonly used. Where the porous tile isused, difliculties have often been encountered with the tiles becom- 111g waterlogged and a consequent sluggish porous clay substance movement of I the water-from the subsoil through the drains. As airemedy for these tlifiiculties, I have constructed a tile which in any type of drainage system where the moisture is to be taken from thesubsoil and atmospheric air supplied thereto. a For the purpose of draining the water, I employ in the horizontal ducts of the system, a tile shown in Figs. 1, 2, 3 and 4 of the drawings.

a This tile comprises two semi-cylindrical portions, 1 and 2, the lower portion havin enlargediflanges 3 along its l'ongitudina edges, WhH'h have flaring lips 3a. The

for this vertical. duct comprises a body por- 'tion"? and a cupsocketportion considered as awhole at 8. This cup socket is formed to IS SlIOWIIIDOTG in detail in Fig. 5. "The tile 7 have a projecting shoulder 8*, adapted to hold the tubular bodyportion of the adjoining tile shown at 7. Z The upper part of this cup socket or that part shown at 8" bell-shaped receptacle about the tubularbody portion of the adj0iningtile: that by using this'type oftile in the vertical It will be readily seen ducts that the molsture and water from the subsoil will collect in the bell-shaped cup formed by the flaring lipyS and will seep down through the tile connections and be drained off through the-system. On' the other hand, in the horizontal ductsor those previously explained, the water will collect in the longitudinal channels 4 and seep down between the upper and lower tile portions and thence be carried off through the drain ducts. V i

In case the soil to be drained is of heavy loam or clay, or any type of soil through Which the moisture does not readily permeate, it may be desirable in laying the tile to place gravel, crushed rock or any granular substance available in the longitudinal channels 4 of the horizontal ducts and in the cup socket portion of the vertical ducts. The use or" this material will materially aid the water in seeping into the channels and cup socket portions and thence into the drains.

As is commonly known, the facilitating of the gress of the water is not alone the essential factor in draining the subsoil but some provision must be made for supplying air thereto. This type of tile lends itself readily to the circulation of air through the crevices between the upper and lower portions of the tile sections of the horizontal ducts and between the tubular body and the cup socket connections of the vertical ducts.

v The drain tile here explained for use in the horizontal ducts of a drainage system areadaptablealso to use in surface drains, the lower portion being sunk in a trench and held fixedly from any rotary movement by the shoulders 3 of the flange portions. Surface drains of this sort could be readily cleaned by merely removing the top section.

In the construction of these tiles I preferably use a vitrified clay which is practically impervious to water and does not readily waterlog. The space between the tile sections made by the tile construction are ample to care for all the water in the subsoil without the necessity of using a porous tile.

In this I do not wish to limit myself to any particular substance in the construction of the tile or to any particular means for collecting the water from the subsoil further than that stipulated'in the specification and claima The advantage in this tile lies solely in the'construction by means of which the subsoil" moisture may be easily collected and drained oft", and at the same time the subsoil supplied with air .by a free circulation through the ducts and crevices especially provided for this purpose.

I claim as my invention:

1. In drain tiles, the combination with a pair of abutting tubular members,.0f an enlarged flange portion secured to the end of one tile member and fitting around the abutting end of th other tile, a cup shaped portion carried by said flange and adapted to collect the moisture from the subsoil and permit the seepage through the tiles into the system. 7

2. In drain tiles, the combination with a pair of abutting tubular members, of an enlarged flange portion at one end of the tile member, a shoulder portion within the flange portion iitting around the abutting end of the other tile, a bell shaped mouth on said enlarged flange portion for collecting the subsoil moisture, and adapted to drain the collected moisture into the system.

3. In drain tiles, the combination with upper and lower semi-cylindrical sections, overlapping flanged sockets on the longitudinal edges of said lower section adapted to carry the upper section, a bell mouthed end connection on the upper and lower sections for uniting the ends by a bell and spigot connection.

In drain tiles, the combination with upper and lower semi-cyliiulrical sections, enlarged overlapping flanged portions on the longitudinal edges of the lower sections, a flaring lip on the flanged portions adapted to collect the subsoil moisture, and means for making end unions of the separate tile sections.

5. In drain tiles, the combination with upper and lower semi-cylindrical sections, overlapping flange portions on the longitudinal edges of said lower section for supporting the upper section, bell mouthed flanges on both the upper and lower sections for endwise connecting the separate tile sections into continuous ducts.

6. In drain tiles, the combination with a tubular body member of a bell mouthed end flange connection adapted to fit the tubular body member of the adjoining tile, :1 flaring lip on each flange connection for collecting moisture therein, and for draining said moisture into the tiles. 7

7. 'In drain tiles, the combination with a tubular body member, of an enlarged cup socket end flange connecting portion comprising an inner shoulder adapted to it around the tubular body member of the adjoining tile and a flaring lip portion forming a cupshaped receptacle about the tubular body of the adjoining tile.

8. In drain tiles, the combiinition with upper and lower semi-cylindrical sections, overlapping flange portions on the longitiulinal edges of the lower sections adapted to sup port the upper section in position on an open joint and permit the ground water collected thereby to flow into the drain, bell mouthed connection on one end of the section adapted to be connected with the adjoining tile sections by a bell and spigot joint.
